A blind person is traveling on the subway. The train they’re riding on pulls into a stop, the doors open and the person exits. Waiting there on the platform, to help guide them through the station, is a robot.“Making a robot do that, there are some challenges, but it’s not as challenging as it used to be,” said Aaron Steinfeld after describing the scenario involving the guide-bot during a recent interview. Steinfeld is an associate research professor at Carnegie Mellon University’s Robotics Institute in Pittsburgh, where he specializes in human-robot interaction.
